Ok, so we have a red-eared slider n hes 7 years old n HUGE, but recently he would NOT stay in his tank, so my mom took him out and got him a pool outside, like a small $5 kiddie pool, and he only likes to stay it in when its warm, BUT now he wont go in his tank, so he just walks around the family room, hes been out of water for MONTHS only getting into that pool like a few times a week for a few hours each time.. But he hasn't eaten anything in maybe 2 or 3 weeks, what do we do!?!? We are scared he's going to starve? we have called Vets and no one seems to have any answers!!
